Building sector sponsored standards survey insights

To support easy access to standards in the building and construction sector, Standards New Zealand has partnered with the building regulator to offer pre-funded sponsored access to over 130 sector-relevant New Zealand standards. This helps those across the sector to do the right thing and comply with the building code.

Building standards remain some of the most popular standards downloaded from our webshop, showing standards are a key part of a practitioner’s toolbox. However, understanding the real value of standards and easy access comes through learning from those across the sector who access and use them.

That’s why in May 2023, Standards New Zealand, in consultation with MBIE Building System Performance (the building regulator), ran a survey of sector stakeholders. The survey sought feedback on:

• How users access, store, and use building and construction standards.
• Where they seek information about designing and constructing buildings.
• The value they place upon having free access to sponsored (pre-funded) standards.
• The benefits of using standards in general.
• Preferences for document format and potential new digital features. 

Some demographic information was also captured, including organisation size and sector. (Note that currently no personal information is collected when downloading a sponsored standard.) 

The survey was sent to over 3,400 people subscribed to building updates on Standards New Zealand Keep-Me-Up-To-Date service. The survey was also sent to industry partners for distribution to their membership/subscribers as part of their regular communications. These included the Association of Consulting Engineers of New Zealand (ACENZ), Engineering New Zealand, Master Plumbers and Building Research Association NZ (BRANZ). 

User experience

When asked to respond based upon their experience with sponsored New Zealand building and construction standards:

• 93% of respondents agreed that sponsored standards made it easier to comply with regulation.
• 91% of respondents recommend the use of sponsored standards to others in their industry.
• 87% of respondents agreed sponsored standards were easy to locate.

Reason for access

Below are the results from respondents who were asked "Why do you usually access sponsored building standards?"

Answer choices	Responses
To show new building plans and specifications are Building Code compliant	64%
To show alteration plans and specifications are Building Code compliant	62%
To construct new buildings	47%
To carry out repairs and/or alterations to existing buildings	53%
To better understand specific types of building work	43%
To find specifications for how building products should be manufactured or should perform	40%
To keep up to date with new industry information	47%
To check that work carried out by others is Building Code compliant	43%
Other (please specify)	5%

Digital formats

Access to building and construction related standards can be made easier through digital formats on smart devices, that users can access on site when needed. This is different to PDFs which do not allow interactive features. To make standards available through digital formats requires dedicated resource and adaptation of content so it is more dynamic and can respond to user needs. We sought feedback to inform the level of desire for digital formats and what this might look like.

When asked what publication formats and features they would like to use:

• 64% of respondents said they would like the ability to zoom in to images
• 48% of respondents would like to easily compare different versions/editions of the same publication (red-lining)
• 45% of respondents would like a built-in calculator for equations to be available within the standard
• 44% of respondents would like the ability to hyper-link from one standard to another

Respondents could select multiple answers. Full results below:

Answer choices	Responses
Digital format designed for a phone-sized screen	40%
Web-browser format for easy consumption on multiple devices	43%
Application-based formats	19%
Ability to easily compare different versions/editions of the same publication	48%
Ability to expand and collapse tables	41%
Ability to zoom in to images	64%
Ability to add and save notes within the publication	39%
Ability to hyper-link from one standard to another	44%
Built-in calculators for equations within standards	45%
Inclusion of 3D rotatable figures	31%
Inclusion of video content	21%
Other (please specify)	12%

 

Other responses for digital formats included the ability to add bookmarks, notes, comments, mark ups etc and search functionality within the document. Some comments include:

• ‘Add notes, comments, drawings, images. It is really annoying to purchase a standard and not have the ability to do mark ups’.
• ‘Books marks to all sections’.
• • ‘Search function, bookmark function, automatic up-date warning’.

When asked if there was anything they want us to know, 53 responses were provided. Overall, the sponsored standards were valuable for users and there was a strong desire to see more sponsored standards, especially those referenced within the Building Code.

Some responses are below:

• ‘Having access to the standards is paramount to ensuring compliance with the standards. If a user has to pay for them, they are not going to bother checking them, especially when multiple standards need to be checked for compliance. It is EXTREMELY valuable having sponsored access to the documents.’
• ‘All standards that are cited in the Building Code documents and acceptable solutions should be sponsored. The ones that are not are usually more expensive Australian or international standards and they cost an arm and leg to access them when you are only trying to comply with and use an acceptable solution.’
• ‘Sponsored standards are very useful for small and young practitioners.’
• ‘Best thing about sponsored standards is that I can send a link to others and know they can access them. Purchased copies can’t be shared and the recipient may decide not to purchase even though I need them to have the information’.
• ‘With the AS/NZS 3500 series being updated every 3 years and being actively referenced in the New Zealand Building Code would be greatly appreciated as being sponsored too as the cost is prohibitive.’
• ‘Appreciate the motivation behind information supporting mandatory requirements. It goes substantially toward having minimum construction and product specifications more easily and affordably achieved.’

Some other highlights of the survey response include:

• 63% of respondents said they would rarely, or not at all, access a building and construction standard if it was not sponsored. 
• 57% of respondents save the downloaded standard on their PC, 20% save it on a cloud environment, 14% don’t save it and download from Standards New Zealand website when it is required and 5% print a hardcopy.
• 75% of respondents go to the Standards New Zealand website to keep informed about regulatory guidance and legal requirements for the sector; 46% go to industry bodies or associations for this information, 43% use internet search and 40% go to the Building CodeHub website. From ‘Other’ responses, the majority of respondents advised they rely on email subscriptions and newsletters from BRANZ, MBIE and Standards New Zealand to keep up to date.
• 55% of respondents had less than 10 staff members in their organisation, another 22% had between 11 and 50, and 23% had more than 100.

In summary

Sponsorship of New Zealand building and construction-related standards seems to provide a clear positive impact for users and the industry. By removing cost barriers to access, significantly more users are willing to access the standard (a twenty-fold increase) and tell us they find it easier to comply with regulation (achieve building code compliance). Access to sponsored standards assisted users in a range of areas including planning and specifications, checking compliance as well as educating, upskilling and research. Users support and recommend the use of sponsored standards to others within their industry which assists with promoting agreed good practice and compliance. While PDF formats continue to be preferred over hardcopies, an emerging interest in digital formats and more sophisticated product features is demonstrated with these results. 

It was surprising to see that more respondents go to the Standards New Zealand website than any other source for regulatory compliance. Since providing regulatory advice is not Standards New Zealand’s role, perhaps more work can be done to redirect the industry to more appropriate sites and resources.

There is a desire to see more standards that are referenced in the Building Code to be made available for free download which suggests there are new opportunities the partnership may want to explore further in terms of both increasing sponsored access and moving into digital formats to support industry’s easier access and utility of the standards.
